PATENT oFFrc E 4. Claims.

This invention relates to an apparatus for spot dyeing skeins of textilematerial, that is,

dyeing longitudinally spaced portions of said skeins either the-same ora variety of different colors or shades.

The invention broadly comprehends an apparatus of the character and forthe purpose'set forth which includes means for sealing off and isolatingone or morelong-itudinally spaced portions of one or more skeins oftextile material Within dye receiving compartments, means for completelyfilling said compartments with dye solution of the same or differentcolors or shades so that said sealed off isolated skein portions areimmersed in 'the' dye solutions, and means for removing the dyesolutions from the compartments to permit of the unsealing and removalof the skeins from the apparatus or the shifting of the same withrespectthereto to dispose other longitudinally spaced portions in a positionfor sealed off isolation and dye ng.

More particularly the invention resides in an apparatus of this naturewhich includes a pair of separable blocks having a plurality of dye re-25. ceiving recesses in the confronting faces thereof between whichfaces the skeins are arranged with portions thereof traversing therecesses, yieldable gaskets being provided'on the confronting faces ofthe dye blocks, framing the recesses 30. together with means forforceably compressing the gasket confronting faces into intimate seal--ing contact to seal off" and isolate'the longitudinally spacedportionsof the skeins, with valved means for gravitationally supplyingdye to and filling the recesses, valved means for'venti'ng. the

recesses and for indicating when the same are filled and valved meansfor draining the excessdye from the recesses after the skein portionshave been impregnated.

The invention furthermore embodies means for introducing air pressure tothe-dye receiving recesses when filled with the dye and sealed so as tomore rapidly effect the impregnation of the skein portions and forsubsequently effecting the removal of the excess dye and causing a morerapid oxidation or setting of the dye impregnated portions of the skeinswhereby they may be removed.

Other features of the invention reside in' an 60. improved apparatus ofthis character by virtue of which the operations of positioning theskeinsfor dyeing, subjecting them to andthoroughly impregnating themwith the dye, effecting the removal of the excess dye therefrom andcaus- 553 ing the oxidizing: or drying of the dye impregn'ated portionor portions of the skeins to permit of their: removal, may beexpeditiously accom-/ plished' without material loss of the dyeingsolutions, while confining the dye more precisely to predeterminedportions of the skeins.

Other objects of the invention are to provide an apparatus of thisnature which is-notunduly' complicated either in its construction ormode of use, which is capable of economical production and assembly andwhich ishighly eflicient for its intended purpose.

Withthese and other'objects'in view; reference is now made to thefollowing. specification and" the accompanying drawings in which: there'is disclosed one embodiment of the invention, while. the claims cover"variations and modifications falling withinthe scope of the invention.

In the drawings:

Fig; 4 is a vertical transverse sectional" view" taken approximately onthe line 4--4 of Fig. 2;

Fig. 5 is a vertical sectional view taken approximately on aplaneindicated by the line 5-5 in Fig. 2;

While obviously the apparatus may be employed-for dyeingoneportionof thelength of one skein at one time, from a practical standpoint itis-herein illustrated and intended to be utilized. for. simultaneouslydyeing a plurality of longitudinally spaced portions of eachof a. numberof skeins, a variety of different colors or shades.

Referring to the drawings by characters of reference, l0 designates thebase of the apparatus which is provided with laterally spaced uprightsupports II and IZhaving, horizontal upper supporting surfaces l3 andI4. A pair of arms l5 and I6 aresecured" to the'supports II and [2respectively and protrude upwardly therefrom, the upper ends'beingprovided with reduced threaded upper extremitiesl-'! which receivethereover the apertured terminals of a cross. head I8 having acentralhub l-B provided with a vertical internallythreaded bore 20. A threadedshaft 21 engages with the: bore 20-, is provided with a manipulatingwheel 22 at its. upper end and is connected at 1 its lower end by:

a swiveled connection 23 with a pressure plate 24 which is mounted forguided vertical movement on the arms I and I6 which extend through guideopenings 25 and 25 in the pressure plate.

The apparatus further includes a pair of dye blocks 30 and 3|, theformer being hereinafter termed the lower dye block and the latter theupper dye block. The lower dye block 30 is provided with a verticalopening 32 through which the arm l5 extends and normally rests upon theupper supporting surfaces l3 and M of the supports H and I2, but iscapable of being swung to a position to disengage the upper surface [4of the support 12 so as to permit of the positioning of the skeinsthereover in surrounding relation thereto. The upper dye block 3| ismounted for vertical guided sliding movement on the arms i5 and it whichextend through vertical guide openings 33 and 34 and said upper dyeblock is detachably connected with the pressure plate 24 by suitablemeans, such as the swinging hooks 35 fulcrumed on the pressure plate 24and engaging with eyes 36 on said upper dye block.

As illustrated, the confronting faces of the upper and lower dye blocks30 and 36 are provided with a plurality of confronting mating recesses4i) and M, 42 and 43, and 44 and 45, it being obvious that one or morepairs of mating recesses may be provided in said dye blocks within thescope of the invention. It will also be apparent that the recesses maybe varied in size as well as the number employed and that the dye :locksmay be of any practical length depending upon the number of skeins whichare to be simultaneously dyed by the apparatus.

The confronting faces of the blocks are each provided with yieldablesealing gaskets 46 and 41 which are provided with mating slots 48 condonning to the contour of the recesses so that the same are framed bythe gasket material which is preferably a good grade of Para rubber andwhich is secured in place in any suitable manner, such as by screws orother equivalent fastening :means '29 which are threaded into woodenplugs 55 counter-sunk in depressions in the confronting faces of the dyeblocks.

The skeins of textile material, which are designated by the referencecharacter S, are preferably arranged in surrounding relation to thelower dye block 30 as particularly illustrated in Fig. 5 of thedrawings, so that the upper leads thereof traverse the upper face of thelower dye block with longitudinally spaced portions P thereof traversingeach of the recesses 45), 42 and 44. The emplacement of the skeins S iseffected by swinging the lower dye block to a position out of contactwith the support l2, as shown in Fig. 3 of the drawings. After theskeins have thus been emplaced, the dye block is swung to its normalposition resting upon and supported by the upper surfaces l3 and I4 ofthe supports H and H2. The upper dye block which has been elevated topermit of the emplacement of the skeins, is then lowered by means of thethreaded shaft 2i and the gasketed lower surface of the upper dye blockis forceably compressed against the gasketed upper face of the lower dyeblock to seal off and isolate the portions P of the skeins S in themating dye receiving recesses 40 and ii, 42 and 43, and 44 and 35, itbeing understood that the yieldability of the gaskets 46 and 41 willpermit them to be compressed and intimately seal about the portions ofthe skeins which are located therebetween and prevent escape of the dyesolution from the dye recesses.

In order to provide means for gravitationally supplying and introducingthe dye to the dye receiving recesses, a dye reservoir 55 is providedfor each pair of mating recesses which is located above the recesses andeach reservoir has leading downwardly therefrom a conduit pipe 56controlled by a shut off valve 51. The conduit pipes 56 are respectivelyconnected to and communicate with ports 58 leading to the correspondingrecess in the lower dye block. Each recess of the upper dye block 3| isprovided with a port 59 with which a conduit pipe 60 is connected andcommunicat'es. The pipes 60 are each provided with a T coupling 6 l, thevertical branch of which connects with a vertical pipe 62 having a cutoff valve 53 from the top of which a combinedtransparent sight and venttube 65 extends upwardly. The remaining horizontal branch of the Tcoupling E5! is connected with a nipple 65 having a check valve 86 whichopens inwardly and closes outwardly. Each nipple is adapted to haveattached thereto an air pressure hose, not shown.

The lower end of each reservoir 55 may be provided with a drain valve 61and the conduit pipes 56 adjacent "leir connection with the lower valveblock have interposed therein a T connection 38, the lower verticalbranch of which connects with a drain pipe 69 having a cut off valve Inop ation, assuming that the skeins have been pOSltiGllCd and clampedbetween. the dye blocks, as shown in Fig. 5, so that the portions P havebeen sealed off and isolated in the dye receiving compartments definedby the mating recesses, the valves El and 15 being closed, the op uc:opens the valves 63 and 51. The dye soluhons in the reservoir which maybe either of the same or different colors or shades, gravitationally runinto the dye receiving compartments.

defined by the mating recesses, completely filling the same as they arevented by the air escaping through the ports 59, the pipes 59, Tcoupling Si, pipes 52, through the opened valves 63 and the combinedsight and vent tubes 84. When the dye shows in the sight tubes 64, theoperator cuts off the valves 53 and 5'! thereby sealing up the dyesystem completely. Air pressure may now be admitted through the nipples65 and check valve 65' to set up a pressure within the system so as toforce and expedite the impregnation of the skein portions P with thedye. The drain valves iii are then opened to permit the dye to bedischarged from the system through the drain pipes 69 where the dye iscaught into receptacles a! placed thereunder to receive the same, theair pressure assisting in a rapid discharge and at the same timeeffecting a more rapid oxidation and setting of the dye in theimpregnated skein portions P. The drain valves it? are then cut off andthe dye solutions in the receptacles H are poured back into thereservoirs 55 so that the operation may be repeated.

As illustrated, the lower dye block 3%] is provided with guide rollers75 around which the skeins are trained and the supports ll and 2 at thefront are provided with vertically adjustable brackets 'i'G which arenormally drawn downwardly by contractile springs "H. A removable roller78 is mounted for rotation in the brackets and is adapted to be turnedby means of a crank '59. The skeins are trained around the roller 78which is employed as a means for shifting the skein to for dyeing.
